    If you buy them in bulk, you can find them for $150.
    Right now powerking sells them for $175 shipped.

    boygofast maybe?

    To Venice Boy- where do you buy in bulk? I have had a few "offers" to buy in bulk for the same or more than I can get them from e-bay. Also the direct route is for a 20'container of 1250 kits!!!!!!! They still have not gotten back to me on unit prices, but I would have to say it would have to be in the 50 dollars per area for it to be considered.

    While some engines are not identicial, the majority of engines are interchangeable. Some parts from same engine marker aren't interchangeable because of the wide variation in manufacturing tolerances.

    I do know that Kings motor parts (piston, cylinder) do not work on Dax motors.

    Just remember that it's not really an 80cc, it's a 70cc engine and they are roller bearings not ball bearings and you'll probably be happy.

    They are available from several sellers on different sites...they are not however 80cc's, unless somebody is boring them out after they get them from China.....you can't bore a Nikasil liner though, so I digress.

    personally i will only by from a dealer i can get support from, i bought from boygofast and it was different then his listing and i was pretty much told to bad. its been a good motor and runs good but had problems with the carb and also the mounts for an oversize frame were not with it and he would not provide the mounts or replace the carb. thatsdax stands behind his products and is thier to answer your questions. that is worth every penny to me.
